The following steps can be used to further pinpoint the problem:
1. Verification: Set the environment variable MALLOC_ARENA_MAX=2 in the
container, re-run the load test, and observe changes in memory behavior.
2. Verification: Manually trigger `collectgarbage()` via the Control API
POST /v1/gc endpoint and observe whether Lua layer memory usage decreases.
3. Monitoring: Compare the return value of `collectgarbage("count")` with
the container's RSS feed to confirm that the difference mainly originates from
the C layer.
4. Optional Optimization: Configure `metadata.max_pending_entries` and a
smaller `buffer_duration` for `loki-logger` to reduce temporary buffering.
